Galois action

Roots of defining polynomial

The roots of $f$ are computed in $\Q_{ 101 }$ to precision 5.

Roots:

$r_{ 1 }$	$=$	$ 30 + 64\cdot 101 + 12\cdot 101^{2} + 40\cdot 101^{3} + 77\cdot 101^{4} +O\left(101^{ 5 }\right)$
$r_{ 2 }$	$=$	$ 55 + 96\cdot 101 + 69\cdot 101^{2} + 91\cdot 101^{3} + 13\cdot 101^{4} +O\left(101^{ 5 }\right)$
$r_{ 3 }$	$=$	$ 57 + 50\cdot 101 + 18\cdot 101^{2} + 28\cdot 101^{3} + 4\cdot 101^{4} +O\left(101^{ 5 }\right)$
$r_{ 4 }$	$=$	$ 61 + 91\cdot 101 + 100\cdot 101^{2} + 41\cdot 101^{3} + 5\cdot 101^{4} +O\left(101^{ 5 }\right)$
